Electric coagulation suction debonder

Abstract

The invention relates to a medical instrument, in particular to an electric coagulation suction stripper which is mainly applicable to paranasal sinus of human body. The electric coagulation suction stripper comprises a handle with a hollow structure, an electronic, a suction joint with a hollow structure and an insulation pipe with high-temperature resistance and high pressure performance and a suction pipe; the handle is arranged between the suction pipe and the suction joint; the electric coagulation suction stripper is characterized in that one end of the suction pipe is provided with a stripping head which is connected with the suction pipe as a whole; the stripping head is provided with an auxiliary suction hole with the diameter of 0.9-1.1mm; furthermore, the end surface of the stripping head and the central line of the suction pipe have the angle of 35-40 DEG. The electric coagulation suction stripper has the advantages of reasonable, simple and compact structural design, realizes the electric coagulation and suction, carries out the stripping at the same time, and has convenient and reliable usage.

Description

technical field [0001] The invention relates to a medical device, in particular to an electrocoagulation suction stripper, which is mainly suitable for sinus surgery of human body. Background technique [0002] When performing human sinus surgery, the nasal bone needs to be separated from the periosteum, the bleeding needs to be sucked out and the bleeding point needs to be electrocoagulated, so an electrocoagulation suction stripper is required. In the prior art, Chinese patent application 200610050577, 9, an invention patent application named "sinus electrocoagulation suction device" is disclosed, which includes a handle with a hollow structure, and is equipped with suction joints, electrodes, thermoplastic tubes and suction tubes at the same time. The suction joint and the handle are connected by thread, the electrode and the handle are also connected by thread, the thermoplastic tube is glued to the handle, and the suction tube and the thermoplastic tube are fixed by soc...

AI Technical Summary

Problems solved by technology

The electrocoagulation suction device of this structure has the following defects in use: its structural design is not reasonable enough, and its functions are few. It only has two functions of coagulation and suction, and it cannot be peeled off. To peel off, other special medical devices are needed, which is not convenient enough to use.

And Chinese patent application 92108653,9, titled "hollow electrocoagulator for otolaryngology", it also has the defects of unreasonable structural design and few functions. Capable of electric coagulation and attraction, unable to peel off, inconvenient to use

Chinese patent application 200420048447, 8, a utility model named "nasal periosteum stripper", which includes a handle and a stripping head, the handle and the stripping head are in one structure, and there is a crescent-shaped gap on the stripping head; but the stripper can only strip, Instead of electrocoagulation and attraction

Although some people have been studying the structure in this area, they finally found that the structure is not reasonable enough, the design is too complicated, the cost is high, and the practicability is not good enough
